There are two areas that I'd re-address, and bear in mind, just my humble opinion, okay? Pump up the contrast on the eyes so you have some solid blacks in the pupils. She looks like she's wearing those mirrored contact lenses one sees in 1980s horror films. The line for the eyebrows is too defined. Loosen it up a bit with a few errant hairs, particularly along the extreme left and right. Those two quibbles aside, it's a nice piece of work. Congratulations.
